1/5 Starswheel weakness5/1/2011 | clydeI love the wheeler rex 4991 close quarters copper tubing cutter, however the wheels are hard to find and very weak. I have used them on type "K" copper and broken the wheel I had to use a saw to finish the job and it made a 1hr. job turn into a 4 hr job. It needs to be thickened to prevent failure when in a tight spot where you cant use anything else.
